I've been trying to get a Drupal/Ubercart site off the ground for a while now and am finally getting close. As such I've been paying more attention to the nitty/gritty bits that are normally overlooked whilst dealing with the bigger picture. Ryan suggested feedback in this area would be very welcome so I figure here's a good place to start a list:
Looks like "You must select a quote before continuing" is located in shipping > uc_quote > uc_quote.module about line 840. Will have to test a text change at that location myself on the localhost machine.

Changed out the text in line 840 in the uc_quote.module on both the localhost and live test server. Seems to run OK on both.
Now using this text in place of "You must select a quote before continuing."
"Please select either Local Anchorage Pickup or Shipping Costs by clicking on the Click to calculate shipping button before continuing."
The only part that would be nicer is that if in addition to the warning displayed on the top of the page would be that the "Calculate Shipping Cost" block would be outlined in red just like when name, address, etc is not entered.

There are a number of user configurable messages located in the administrative section as follows:
admin/store/settings/checkout/edit/messages
Have not changed any of these myself, but it does look like the text can be changed to fit your needs without getting into any of the module code.
